But as expensive as constant load-shedding? Unlikely.

Independent energy analyst Clyde Mallinson tells Peter Bruce in this edition of Podcasts from the Edge that, starting tomorrow, South Africa could begin, at pace, to install up to 35,000MW of renewable storage by 2035 to completely solve our power problems.

Obviously in addition to ramping up solar and wind investment as well. While the government and business slow-talk their way through our crisis, the answer is right in from of us.
